Small-scale wireless magnetic robots and devices offer an effective solution to operations in hard-to-reach and high-risk enclosed places, such as inside the human body, nuclear plants, and vehicle infrastructure. In order to obtain functionalities beyond the capability of magnetic forces and torques exerted on magnetic materials used in these robotic devices, electronics need to be also integrated into them. However, their capabilities and power sources are still very limited compared to their larger-scale counterparts due to their much smaller sizes. Here, groups of milli/centimeter-scale wireless magnetic modules are shown to enable on-site electronic circuit construction and operation of highly demanding wireless electrical devices with no batteries, that is, with wireless power. Moreover, the mobility of the modular components brings remote modification and reconfiguration capabilities. When these small-scale robotic modules are remotely assembled into specific geometries, they can achieve, if not impossible, challenging electrical tasks for individual modules. Using such a method, several wireless and battery-free robotic devices are demonstrated using milli/centimeter-scale robotic modules, such as a wireless circuit to power light-emitting diodes with lower external fields, a device to actuate relatively high force-output shape memory alloy actuators, and a wireless force sensor, all of which can be modified on-site.

用于无线磁性设备的远程模块化电子设备

小型无线磁力机器人和设备为在人体内、核电站和车辆基础设施等难以到达和高风险封闭场所的操作提供了有效的解决方案。为了获得超出施加在这些机器人设备中使用的磁性材料上的磁力和扭矩能力的功能，还需要将电子设备集成到其中。然而，由于它们的尺寸要小得多，与大型同类产品相比，它们的能力和电源仍然非常有限。在这里，展示了几组毫/厘米级无线磁性模块，以实现现场电子电路的构建和高要求的无线电子设备的运行，而无需电池，即无线电源。而且，模块化组件的移动性带来了远程修改和重新配置能力。当这些小型机器人模块被远程组装成特定的几何形状时，即使不是不可能，它们也可以为单个模块完成具有挑战性的电气任务。使用这种方法，几个无线和无电池机器人设备使用毫/厘米级机器人模块进行演示，例如为具有较低外部场的发光二极管供电的无线电路，一种驱动相对较高的力输出形状的设备记忆合金致动器和无线力传感器，所有这些都可以在现场进行修改。具有挑战性的单个模块的电气任务。使用这种方法，几个无线和无电池机器人设备使用毫/厘米级机器人模块进行演示，例如为具有较低外部场的发光二极管供电的无线电路，一种驱动相对较高的力输出形状的设备记忆合金致动器和无线力传感器，所有这些都可以在现场进行修改。具有挑战性的单个模块的电气任务。使用这种方法，几个无线和无电池机器人设备使用毫/厘米级机器人模块进行演示，例如为具有较低外部场的发光二极管供电的无线电路，一种驱动相对较高的力输出形状的设备记忆合金致动器和无线力传感器，所有这些都可以在现场进行修改。
